BROOKLYN, NEW YORK, ASSIGNORS `TO DENSMORE YORK, A CORPORA- TYPE-WRITING MACHINE.

To all whom it may concern.-

Be it known that we, HENRY W, Mnanrr'r, a resident of Sprin field, county-of Hainpf den, and State of assaehusetts, and WALf, TER J. Brannon, a resident of the borough of Brooklyn, county of Kin s, city and State of New York, citizens of the Tnited States, have invented certain new and useful Improve-j ments in Type-Writin Machines, of which the following is a speci cation Our invention relates to type-writing machines, and more particularly to the line-lock mechanisms thereof.

The main ob'ect of our invention is to provide simple an efficient means whereby the type-carriers through their actuating mechanism may be automatically locked against printing movement at any predetermined point in the travel of the carria e and after- Ward released by hand-operate mechanism should the operator desire to write one or more additional characters to the line to cornplete a word or sentence.

A further object of the invention is to provide in addition'to the mechanism above-'referr-ed o a second device by which the linelock is actuated to lock the type-carriers out of action at the extreme end of the line.

Another object of the invention is to rovide mechanism whereb a movement cip the ca rria e-release key is e ective to automatically re ease the line-lock mechanism. Still another object of the invention is to provide means whereby the lock-line mechanism may be released or unlocked by the depression of a special finger-key at the keyboard.

further object is to provide 4means for permanently maintaining the line-locking mechanism out of action should that be the desire of the operator.

To the ends above speciiied and others, which will appear in the following specification, the invention consists in the novel features of construction and arrangements and combinations of parts hereinafter described, and particularly pointed out in the appended claims.

In the accompanying drawings, wherein like reference characters represent corresponding parts in the various views, Figure 1 is a vertical sectional view of a type-writing machine embodying our invention, the sec- Speccaton of Letters Patent.

Y tion being taken from front to rear of the mabine, lig. 2-is a detail sectional side view of a portion o the linelockmeloasing mech- Ilanisrn and of the means for maintainin the line-lock mechanism permanently out o action. Fig. 3 is a detai side view of the springdrum and its cooperating adjustable trip mechanism. Fig. 4 is a rear view of the machine, partly in section, Figs. 5 and 6 are detail perspective views of parts of the mechanism to be hereinafter described.

In the various views arts are omitted and broken away to more c early illustrate other features.

lVe have shown our invention in its a plication to a Densmore type-writing mac ine, though the drawings do not represent in detail certain features of said machine. Thus, for instance, the carriage is not that of a Densmore machine, but is a conventional carriage which may suilice to illustrate our invention.

The main frame ot the machine is indicated at 1 and this frame is rovided with the usual top plate 2, and keyevers 3 are pivoted to the training of the machine', as indicated at 4. rThese key-levers are provided with the usual finger-keys 5 and are connected to links 6,

,which in turn are pivoted to intermediate links or levers 7, that are operatively connected to type bars or carriers S, each of which is pivoted to a hanger 9, as indicated at 10. A single type-bar and its cooperating mechanism is shown in Fig. l of the drawings, that being sufficient to illustrate the invention. Each of the key-levers 3 is likewise provided with a` hook l1 which is adapted to ear upon a universal bar l2, that is pivoted to the framing of the machine at 13 and is connected by a link 14 to a crank-arm l5, that projects from a rock-shaft 16 of a feeddog carrier 17. `The reed-dog carrier 17 may he provided with the usual feed-dogs 18, which cooperate with a feed-wheel 1Q, that is secured to one end of a rotary shaft that turns in a hearing 20, which is secured to the top plate 2 of the machine. The opposite end of this rock-shatt rhas secured thereto a feed-pinion 21, that meshes with the feedrack 22, which is rigidly connected to arms 23, that are secured to a rock-shaft 24, which turns or rocks in a carriage 25, which moves IFC i the carriage to run with relation tively to the 437 with the stpring-drum.

from end to end` of the machine upon a traverse-rod 26 and carries a platen 27. One end of the rock-shaft 24, to which the feed-rack is connected, is provided with. a carriage-release key 28, by means of which the rack can be elevated, thereby releasing` it from engagement with the feedinion 21 and ermitting eely. from end) to end of the machine. The carriage 25 is moved in the direction oflits feed by a spring-drum 29, Which is connected to the carriage by a band 30, said band bein connected atene end 31 to the carriage and; at its opposite end 32 to the drum, which under the tension of its s ring rotates in the direction of the arrow in Pig. 4 when the carria e moves in the direction of its feed. The frum 29 has rigidly secured thereto at 33 a ratchet-wheel 34, andcoperating with this ratchet-wheel 34 are two ivoted spring-pressed pawls 35 and 36, which are pivoted to a plate 37, that is adapted to turn on the same axis that the drum revolves upon. The disposition of these pawls to the teeth on the ratchetwheel is such .that the plate 37 may be turned with relation to the drum in the direction of the arrow in Fig. 4, but cannot turn with relation thereto in an opposite direction. The plate 37 is provided with a lateral projection 38, that constitutes a iingerieee by means of which the late 37 may he turned reladlium. Loosely pivoted to the plate 37, as indicated at 39, is a trip`40, which is provided with a laterally or forwardly projecting trip-pin. 41, and the free movement of the trip 40 on its pivot in opposite directions is controlled by a stop or pin 42, which is carried upon the plate 37 and is adapted to cooperate with portions 43 and 44 on the trip in accordance with the different positions that said trip assumes in the rotation of the plateI From the oregoing description it will `beA understood that the trip 40 is a gravity-.trip and that the position thereof with relation to the plate 37 is altered as the plate 37 revolves with the drum. This is in order that the trip may be maintained in a position to engage its cooperating mechanism when .the 'drum is revolved in one direction, but is free to be deflected to one side when the spring-drum is revolved in an opposite direction, as will hereinafter more clearly ap ear.

Upon reference to igs. 1 and 3 of the drawings it will be observed that the spindle which constitutes a bearing for the spring- Adrum has secured thereto a bell 45, and cooperating with this bell is a bell-trip hammer 46, 4, so that when the carriage is moved in the direction of its feed the spring-drum wil'l rotate in the direction of the arrow in Figifi, thereby bringing the face 47 of the trip into contact with the trip-hammer 46 of thebell, and the hammerwill vibrate with its spring stem or support 48 after the trip l Ilias released it, thus enabling the hell or alarm to be sounded. The spring-drinn 29 is likewise provided with whatwe terni a fixed trip 49, which is or may bc rigidly secured to the drum.

From an ,examination of Figs. 1 and 4 of the drawings it will be observed that a locking-bar 50 is pivoted to the framing of the machine ut 51 and extends beneath all of the key-levers 3. it will likewise he seen that the key-levers 3 are each notched at 52 and that the various notches in these key-levers are in alineinent and when the parts are in the position indicated in Figi l ol' the drawin s the key-levers 3 are free to he depressed. Willen, however, the loeking-bar`5() has been moved in the direction of the arrow in Fig. 1 it will be movel'dfrom a position opposite the notches 52 inthe key-levers to a position where the upper ed le of said locking-har comes directly beneat i the lowerpdgc of each of the key-levers, thus locking them or preventing a depression thereof. The lockingbar 5U is normally maintained by its own weight and the weight of the parts connected thereto in the osition rc resented in Fig. 1 where the key-lhvers are Aree to bc operated or depressed. The lockii'ighar 50 may he moved to the locking position by any one of several mean which will now be pointed out. The lockingar is provided with an angular projection or flange `53, from which extends an ear 54, carrying/a pivot 55, to which is connected an upwardly-extending rod 56, havin at its upper end a hook 57, which is provi ed with an inclined face 58. This ook is normally maintained in the position shown in Fig. 4, wherein it is in the tri -pin 41 on the trip 40 when the pin is rotate( with the drinn 29 in the direction of the arrow. The pivotal connection 55 between the rod 56, that carries the hook 57, andthe locking-bar is such, however, that an inward or lateral movement of the hook in the direction of the arrow- 2 is permitted for purposes which will presently appear. It will be understood that when the drum 29 with the trip 4() revolves in a direction o posite to that indicated b i the arrow in Fig. 4 the pin 41 of the trip wi l contact with the inclined face or nose 58 on the hook and the trip will be deflected or turned slightly on its pivot without moving the hook and without obstructing the free movement of the drum, the pin riding down the inclined face of the hook and the trip-piece or plate falling back to normal position by gravity as soon as the pin passes off the hook. When, however, the carriage moves in the direction of its feed and the drum revolves in the direction of the arrow, the tiip-pin 41 on the trip 4U wiltengage the hook 57 at a point in the feed of the carriage which is determined by the adjustment of the plate 37 with relation to the drinn 29. After such engagement between the pin 41 IOC the path of f smi 53 and the hunk 57 has taken Place a further slight` movement of the pin will suflice t@ liftr the od .56 and move the locking-bar 5D imm beneath the nuclied portions of the 1&951194 vers lw locking; pasiticm zidi in d ted lines at 2 L@ iis i@ peviit il. n simi mi' l" lie in) -levirs ami a mmv:

This same pressure upon the permanent release-key 8l causes the hook S5 to engage the late SG, as shown in Fig. 2, thus lockin f the ever T5 in the depressed position an( the hook 57 out of the path of travel of the pin il and preventing'a return movement thereof. ihile the parts are in these positions the machine may be o erated indeiinitely without using the lineocking mechanism at all, it being understood that some operators prefer not lo use a line-locking mechanism. Then the operator desires to release the permanent releasc-lieyl from this engagement, it is merel)r necessary to slightly depress the teinlnnnryY release-key 74, when the hook $5 will be disengaged from the plate 86 and the key-lever 75 with key S1 is free to be elevated to the norma] or disengaged position.

ln addition to the line-locking mechanism hereinl'iel'ore referred to there is provided a second or permanent line-locking device, which is controlled b v the trip or arm 49. The purpose of this permanent line-lock is to prevent the key-levers from beimlr actuated when the` extreme end of the line 1s reached, irrespective of all other conditions. lf, for example, the adjustable device 3T, Carrying the actuating-pin. 41, be set to lock the lreylevers against movement when the carriage has arrived at the point (it) on the carriagesrale and the key-levers be unlocled by a depression of the temporary release-key 74, the operator mayr proceed to write additional characters upon the line; but when the carriage reaehes the extreme end of the line, or the limit of movement of its travel, the permanent line-locking device will come into action and the key-levers will again be prevented from being depressed, thus obviating a piling up of the characters on the paper at the end of the line. It will be understood that the pernnment trip 49 is secured to the drum 29 at a point which will bring it into engagement with its coiiperating mechanism w ien the end of a line is reached, and hence when the trip 49 has moved with the drum 29 to the position indicated in dotted lines in Fig. 4 of the drawings it will contact with a pin S7 on a vertically-movable rod 88, which 1s guided in its movement by a pin-and-slot connection S9 9U, the )in 89 being carried upon an arm Q1, which extends from the bracket 6T, whilefthe slot 9() extends longitudinallyY in the rod. The lower end of this rod projects through an opening in the flange 53 of thc loek-ing-bar .50. and said rod. is provided with a suitable stop or enlargement 93. By this arrangement it will be seen that the flange 53 maymove with. the lockingbar 5() independently locking-bar is actuated by the hook 57 and its co erating adjustable trip. W`hen, however, tlie iixed or permanent trip 49 actuates of the rod 88 when the.

the rod 88 bv lifting it, the locking-bar .-50 6 will be rocked on its pivots so as to convey it away from the notches 52 in the key-levers, and thus maintain it in the lookin position until the carriage is moved by han: from the extreme left-hand position, where this lastmentioned locking action has taken place. liVhen the carriage is moved back toward the starting-polnt by hand, the permanent lock ing-trip 49 will be moved by the drum in a direction opposite to that indicated by the ar row in Fig'. 4, thereby releasing the rod 88 and permitting the locking-bar to resume its normal position when the key-levers are free to be depressed.

It will be understood that by employing an adjustable deviee,`such as the trip 40, for actuating the locking mechanism at any desired oint in the travel of the carriage and embodying in combination therewith a fixed or permanent trip 49, which will always actuate the locking mechanism at the end of a line or the extreme limit of travel of the carriago in the direction of its feed, means are provided for locking the line first at any predetermined point and then again at the extreme limit of travel of the carria e in case the first linedocking means shou d be unlocked and. the carriage fed. down as far as it is possible for it to go, and thus insuring against printing one letter over another when the carriage has been arrested by the stoppage of its driving-druin at either of the two points referred to.' Vt'ith the aid of this mechanism it unnecessar)v to provide a carriage-stop for limiting the movement of the carriage n1 the direction of its feed, the pin 43 and hook 57 and arm 49 and pin S7 with their associated devices serving to arrest the carriage-feed drum as well as to lock the key `levers and ty e-carriers out of action and prevent a furt er feed movement of the carriage. t

The various key-levers may be normally maintained in the elevated positions bv wire (Ji-springs Q4, each of which is operative v connected at one end to ay keydsver. Phis connection may .be made by bending que end of the spring in the form of a fork 95,,whicl1 is adapted to engage in a notch 96 in each keylever. The o )posite lower end of the C spring may be bent to form aneye 97 through which is passed the shank of a headed screw 98, that engages the threaded hole in a flauwe or other fixed portion 99 of the machine. t will be observed that by this construction a simple, spring is provided for each key-lever and that the tension of such spring may be varied by its adjusting-screw which at the same time constitutes a support for the lower end of the spring.

While the improvements have been shown as applied to a Densmore ty e-writing machine, it shouldbe understood) the"` they are IOS IIO

` in no Sense limited te sueh e, mehine and that certain features may be needV Witheet ether-s.

Xhile we here described the trip 49 as heing;`r fixed to the drum 29, it is obvious that said trip may he medeedjustabie, so that the 0 )ereter may change the extreme length of t e linee, it being understood that the trip 49 ie intended tu operate at the end nf a line whatever the length of the line may he.
